Application filed February 27,1923. Serial No. 621,538.

To all whom z't may concern.

Be it known that I, HAROLD JOHN KINS- MAN, a subject of the King ofEngland, residing at Tredourva, Melville Road, Falmouth, England, haveinvented certain new and useful Improvements in Golf Clubs (for which Ihave filed an application in England 14th February, 1922, Serial No.151452), of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to golf clubs provided with a guide line on theface or top to indicate the initial direction of the ball, the object ofthe invention being to provide an improved combination and arrangementof such lines by the aid of which the performance of variations in thenormal stroke may be effected with ease and efliciency.

According to the present invention, in addition to the known guide linein a plane which is normal both to the striking face and to theaddressing surface there is also provided one or two lines inclined atan angle to the guide line and preferably meeting the latter at thepoint where it joins the edge of the surface bearing it. Preferablythere are two such inclined lines, one on each side of the guide lineand conveniently both at the same angle thereto, their object being toenable the player either to'slice or to pull the ball should he sodesire.

The guide and inclined lines are preferably substantially central inrelation to the striking face of the club, and additional guide linesmay be provided on either side thereof. The central guide line indicatesthe normal strikingportion of the club, the additional guide lines beingfor use when it is desired either to increase or to reduce the travel ofthe ball by striking it at a spot further from or nearer to the handleshaft. Inclined lines may also be provided for each of the additionalguide lines if desired.

In the accompanying drawings Figure 1 is a perspective view showing thestriking face and the top of the head of a driver according to thepresent invention.

Figure 2 is an elevation of a face of a lofting iron according to thepresent inven tion.

Like letters indicate like parts throughout the drawings.

The driver illustrated in Figure 1 is provided with a known guide line Aon the upper surface of its head, the line A being in a plane which isnormal both to the striking face B and to the addressing surface C. Oneach side of the guide line A there is provided a line D and Erespectively, iniclined at an angle thereto. The two inclined lines'Dand E are preferably disposed asil- 'lustrated meeting the guide line Aat the point F where :it joins the front-edge of the surface bearing it.The three lines A,.D, and E thus form an arrow head, and in playing thenormal stroke of any club, the

guide line A corresponding to the stem-of the arrow is contained in thepath of the head; when the stroke is so played the initial course of theball will be in the'same vertical plane as the continuation of the lineA. The object of the inclined lines D and E isto enable the playereither to slice or to pull? the ball should he so desire for whichpurpose these inclined lines indicate the path in which to swing theclub whilst addressing the ball and in making the initial portion of theswing, whilst the guide line A will indicate in all cases the path whichthe head of the club should take during the coneluding stages of thestroke. The mental image given when addressing a ball by the inclinedand guide lines of the angular deflection required in the path of thehead of the club will persist during the stroke and form a considerableaid to the player in controlling such path in the desired manner.

In addition to the guide line A, with its inclined lines D and Edescribed above, which line also indicates'the normal striking portionof theclub, one or two additional guide lines may be also provided;preferably there are two such additional guide lines G and H asillustrated one on each side of the normal one, their object being foruse when it is desired either to increase or to reduce the travel of theball by striking it at a spot ontheclub head further from or nearer tothe handle shaft. Such additional guidelines may also be provided asshown in Fig. lwith like inclined lines to those described above andillustrated at 'D and E, although it is generally found sufficient onlyto provide the inclined lines in respect of the central guide line A,since when using either of the other guide lines the central inclinedlines can be used 'to assist in controlling the path of the club head. a

guide line on one face thereof in a plane normal both to the strikingface and to the addressing surface, of a line inclined to the guide lineon one side thereof and intersecting it at the edge of the face.

2. In a golf club the combination with a guide line on one face thereofextending to the front edge of such face in a plane normal both to thestriking face and to the addressing surface, of a line inclined to theguide line on both sides thereof, the two inclined lines meeting theguide line at the point where it joins the edge of the face bearing it,substantially as specified.

3. In a golf club the combination with a substantially central guideline on one face thereof extending to the front edge of such face in aplane normal both to the striking face and to the addressing surface, ofa line inclined to the guide line on both sides thereof, the twoinclined lines meeting the guide line at the point where it joins theedge of the face hearing it, and an additional guide line on either sideof the central one and parallel thereto, substantially as specified.

4. In a golf club the combination with a substantially central guideline on one face thereof extending to the front edge of such face in aplane normal both to the striking face and to the addressing surface, ofa line inclined to the guide line on both sides thereof the two inclinedlines meeting the guide line at the point where it joins the edge of theface hearing it, an additional guide line on either side of the centralone and parallel thereto, and a line inclined to and meeting suchadditional guide line, substantially as specified.

5. In a golf club the combination with a substantially central guideline on one face thereof extending to the front edge of such face in aplane normal both to the striking face and to the addressing surface, ofa. line inclined to the guide line on both sides thereof, the twoinclined lines meeting the guide line at the point where it joins theedge of the face bearing it, an additional guide line on both sides ofthe central one and. parallel thereto, and lines inclined to and meetingsuch additional guide lines, substantially as specified.

In testimony whereof I hereunto affix my signature.

HAROLD JOHN KINSMAN.
